The 2SD2210 appears in this 46.9 KB PDF with an E suffix in the name that is left unexplained. It is indexed as a schematic but is most likely a datasheet for an NPN bipolar transistor, as the JIS 2SD code indicates a low-frequency NPN device. Check the pinout, VCEO, collector current and hFE grade here before replacement. Make sure the printed code and package of the original component agree with the document.
